摘要
DF100A型100 kW短波发射机调谐系统在发射机中发挥着重要作用,它控制着频率合成器输出相对应的激励信号频率,可完成10个预置调谐频道的定点位置的设置,实现调谐元件的粗调和细调,由此可见各个调谐元器件的位置决定着发射机能否正常稳定运行,直接影响着电台的安全播音工作。为此,通过对DF100A型100 kW短波发射机调谐系统的研究,自主开发组建了一个标准的DF100A型100 kW短波发射机调谐系统教学和测试平台,文章重点介绍其构成、主要内容、特点及应用情况。
DF100A 100 kW shortwave transmitter tuning system plays an important role in the transmitter.It controls the frequency of the excitation signal corresponding to the output of the frequency synthesizer,and can complete the setting of the fixed position of 10 preset tuning channels,so as to realize the coarse and fine tuning of the tuning elements.It can be seen that the position of each tuning element determines whether the transmitter can operate normally and stably,and directly affects the safe broadcasting work of the radio station.Therefore,through the research on the tuning system of DF100A 100 kW shortwave transmitter,a standard teaching and testing platform for DF100A 100 kW shortwave transmitter tuning system has been developed and set up.The composition,main contents,characteristics and application of the platform are mainly introduced.
